HEATING S'IA'OVE OR FURNACE.

BP'ECIPICATION forming part of Le :ters Patent No. 358,432, dated March1, 1887.

Application filed October 24,1825- Serial No. 180,824. (No model.) i

To all whom it may concern:

Be it known that I, LYMAN 1?. OonvERsE, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a certain'new and useful Improvement in Heating-Stoves, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to heating stoves or furnaces wherein thesurrounding air is conducted through a suitable conveyer orconveyersinto an air-heating chest or receiver forming a part of theinterior thereof, and from thence discharged into the room or roomswhich it is desired to heat thereby; and it consists in the combinationand arrangement of devices hereinafter set forth, and pointed out in theappended claim.

In the drawings, Figure 1 is a sectional elevation of a stove, takencentrally through the doors and smoke-escape'pipe, showing my invention;Fig. 2, a sectional elevation thereof, taken on the line XX of said Fig.1; Fig. 3, a transverse section taken on the lineY Y of said Fig. 2.

Within the casing A, at a suitable distance above the fire-pot J, islocated the air-heating chest or reservoir B, which is a simple shell ofcast or sheet iron, preferably having its upper and lower portions 1) bof convex and concave shape, respectively, and being of such diameterwith relation to the diameter of said casing that in its suspendedposition the products of combustion passing from the fire-pot completelyencircle and heat its exterior surfaces. Gonnectedwith said chest orshell are one or more cold-air-induction pipes, O, which extendtherefrom downwardly to a point at or about the base of the stove, and,being suitably fixed to and sustained by the casing A. form at the pointof their connection with said chest or shell a sufficient supporttherefor.

From the upper or convex portion of said chest or shell B is extendedupwardly a cylindrical hot-air-eduction pipe, B, which is sustained,preferably at about the middle of its length, by a diaphragm, D, and atits upper end by the plateforming the upper end of the stove-cylinder.Within the interior of said chest or shell, and forming a part of theupl per or lower portions thereof, as may be most desirable orexpedient, are located a series of irregularly-broken annular ribs orflanges, b, the office of which is to deflect and retard the passage ofthe air in its travel from the induction-pipes Gthrough said heatingchest or shell to the eduction-pipe B.

.l.he diaphragm D, provided with suitable smoke-escape openings, beinglocated about midway the distance between the chest or shell B and thetop of the stove, prevents the products of combustion from rapidlypassing to the smoke-escape pipe E, the result obtained thereby beingthe heating of the eduction-cylinder above and below said diaphragm andthe air passing through its interior more thoroughly than would be thecase if such diaphragm was not present.

The operation of my invention is as follows: The chest or shell B beingheated, the cold air is drawn through the induction-pipes, G, and inpassing therefrom through said chest or shell is deflected through andaround said irregularly-broken annular ribs or flanges b, so that itcomes in contact with the entire heatingsurface of said chest, thencepassing through the eduction-pipe B to the point or points of dischargeat or about the end of said pipe, or T through the upper cap of thestove, as shown.

It is obvious that with the arrangement herewith shown and described amuch greater amount of heat can be obtained from any style of heatingstove or furnace and with a more economical use of fuel than isordinarily and necessarily employed.

Having fully described my. invention, what I claim as new, and desire tosecure by Letters Patent, is a In a heating-stove, the combination, withthe fire-pot J and casing A, of a concave-convex air-heating chest, B,suspended centrally over the fire-pot and communicating with the outerair, and provided internally with irregularlybroken annular flanges b, aconduit, B, leading from the chest B into the apartment to be heated,containing the stove, and a perforated diaphragm, D, surrounding theconduit B within the casing A above the chest B, substantially asdescribed.
